I remember my brother built a binary/octal/decimal/hexadecimal converting computer using ic’s hand wrapped on perf board when he was an 8th grader because he got into an argument with his math teacher over letters being numbers (hex) and not just as a variable. It took him a week to design, and 2-months to build, he took 2nd place at the regional science fair (losing to a bubble memory demo the kid’s dad brought in from his work) My brother used switches to cycle through the modes and lamps to show the converted binary and red digital displays for the hex numbers. There was a keypad to enter the base 10 number to convert. The 80’s were a great time to be a kid. I thought it was cool.

We built breadboard computers like this in high school (mid-80's). We were put into groups of 3-4 people, given the schematic, BOM and told to go build it. The design used a 74181 as the brains. We didn't have a display and all we had for output were LEDs and 7-segment displays. LCD? LOL. FWIW this was a few years before VGA was even a thing. I don't think any group actually got the whole thing to work but some groups got some sub-systems to work.

I started something similar a few years ago. I only used ICs when I'd already built the equivalent with transistors - so an IC with 8 AND gates could only be used once I'd built a few AND gates without ICs. Started from limited electronics knowledge and got as far as having a circuit producing the Fibonacci sequence with LEDs displaying memory content. So at that point I had basic memory handling and felt I understood everything I needed to do to get a working computer but gave up at the point of defining an instruction set. The initial aim was to achieve that level of understanding so I wasn't convinced I wanted to keep adding breadboards having achieved my aim. So your collected mass of breadboards brought back memories. I think this is a great thing to have a go at for anyone with enough interest; even if you don't take it all the way.

First of all amazing work. Similar project was part of our Computer Architecture curriculum, We had to do it in groups of three, within 48 allocated lab hours, over span of two months, the trick is to use single solid core cables, cut them up to desired length and lay them out on breadboard like PCBs. My finger tips just got sore, thinking about all the wire bending i had to do.

Much respect!

Now move the computer to a PCB so it doesn't start failing when you accidentally touch one of the cables :)

That thing is cool! I can't imagine how many hours you spent on working on that just to make it out put hi on the screen. That must have taken a long time, and probably a lot of debugging to say the least. Really cool that it works and man it looks pretty complex dispite its simple instruction set. I will be checking out the hour long video as well because I'm interested in how this works in more detail then whats shown here. Awesome job on the content and I really enjoy your videos!

You are practicing a lost art, my man! Sure, it's a relatively simple computer, but I imagine a day when, given enough knowledge, one might have enough components available to build a more complex system.

But it goes one step farther than jdh has, so far - building a high-level language compiler for it. Maybe if jdh doesn't go there, then I, an electrical engineer, might.

I'm embarking on a similar project to build a custom CPU, but my first effort will be to build it using an FPGA dev board. I'm still debating on the design and I found your lessons learned very helpful. I've especially wondered about whether to include stack instructions and a stack pointer. I'm leaning toward the simplest instruction set and incorporating macros into the assembly language for things like the stack and subroutine call/return. It will save some logic gates at the expense possibly of a bit of speed.

I was working in 2000 on a computer system which when I found main box and found all these circuit boards just like you had and a small controller.. it operated the elevator system.. wow, we pulled it out and installed proper system. I still remove all the wires and circute boards, but to be hones it worked.. Downey California u

So I've been looking forward to this update for a while now. But I think I speak for everyone when I ask when the production run on the custom GPU will finish? I was planning to buy something from AMD, but given how fast these videos are coming out I'm betting yours will be in stock first :P

At 11 minutes when you were going over your regrets about not just using an already built ALU chip it sparked a thought that since you built the ALU from scratch, why not just keep breaking it down until you're building everything from scratch, including your own logic gates. Next video will probably be you gathering sand on the beach then melting it down yourself and forming the silicon into your own chips lmao

The closest I came to a breadboarding a project of this magnitude was the design laid out in "The 8088 Project Book" by Robert Grossblatt. This design will, however, instill the fundamentals and mindset of basic microprocessor operational principles.

This is certainly an ambitious effort nevertheless! Great job!
